Macellum

A macellum is an ancient Roman indoor market building that sold mostly provisions.

A macellum is a fairly easy building to identify from its design. A macellum provides shops arranged around a courtyard which contains a central tholos. The tholos is a round structure, usually built upon a couple of steps (a podium), with a ring of columns supporting a domed roof. A macellum is usually square in shape. (wiki)
